Types of Short Circuit Short circuit of the lithium-ion battery can be divided into ISC and ESC depending on where it occurs, as shown in Figure 1.ESC (A) usually refers to the direct connection between the positive and negative terminals outside the battery (Zavalis et al., 2012).).
batteries
Without further details it is difficult to tell. Anyway, there is a BIG caveat: jump starting a veichle requires very high current spikes, and the cells in the string must be able to withstand it. If the lead acid batteries you will use are of the starter type (and not of the deep cycle type, as used e.g. in UPSs) they are designed to provide current pulses that …
Charging lead acid batteries in series
It is normal to charge lead-acid batteries in series. As they are used, the cell voltages will change, which is why they are not charged in parallel. If they were charged in parallel, the one with the high voltage wouldn''t get much current, and the one with the …

This, in the most port is correct within the limits required for lead-acid batteries. The mathematical equation is: - Open Circuit Voltage = Specific Gravity + 0.84.
batteries
If a car battery is short circuited with a wrench that has 0.5 ohms resistance, then theoretically using Ohm''s law the current = V/R = 12.65 volts / 0.5 ohms = 25.3 amperes. Many people (even on this site here) claim that 100''s to 1000''s of amperes will flow through the wrench and weld it to the terminals.
